Carbon Additive
Used as additive in steel making process. Material quality categories are based on the level of carbon i.e.Super high grade(Fc≧95%),1st Grade(Fc≧94%),2nd grade(Fc≧93%),3rd grade(Fc≧90%).The recarburising efficiency of the super high grade is almost as good as Petcoke material of FC98% ,but the price is as low as or even less than half of Petcoke material.There for this coal-based recarburiser is widely accepted as an alternative material to Petcoke material to be used in the industry.
